摘要： Methods of remotely, selectively controlling the flow rate of fluid moving through a subsea pipeline during dewatering of the pipeline involve a control unit of a subsea valve actuation system selectively, autonomously varying the flow of fluid through a fluid flow conduit of the system fluidly coupled to the pipeline at the pig receiving end thereof based at least partially upon one or more signals emitted by at least one pressure transducer or flow meter fluidly coupled to the fluid flow conduit.

摘要： Methods of remotely facilitating the transition between hydrotesting and dewatering of a subsea pipeline include a control unit of a subsea valve actuation system determining when hydrotesting of the pipeline has been completed and autonomously allowing fluid flow out of the pipeline at the receiving end thereof without the involvement of an external source at the surface, or a UV, at the pig receiving end of the pipeline to allow dewatering the pipeline from the launch end of the pipeline.

摘要： Methods of remotely facilitating the transition between flooding and hydrotesting a subsea pipeline include a control unit of a subsea valve actuation system closing off fluid flow out of the pipeline at the receiving end thereof based at least partially upon one or more signals emitted by at least one intelligent pig that has passed through the pipeline during flooding and without the involvement of an external source at the surface, or a UV, at the pig receiving end of the pipeline.
